摘要

Purpose

Augmented reality (AR) enables real-time overlay of digital information onto the physical environment and may facilitate remote procedural instruction. This pilot randomized controlled trial evaluated the feasibility and short-term performance outcomes of AR-enabled remote proctoring for intraosseous (IO) access training during a surgical intern bootcamp, compared with traditional bedside instruction.

Methods

Incoming PGY-1 general surgery residents participating in a standardized intern bootcamp were randomized to either traditional bedside proctoring (control) or AR-enabled remote proctoring using the Microsoft HoloLens (intervention). All participants received the same standardized procedural demonstration and checklist-based instruction prior to guided practice. Procedural performance was assessed immediately after training using a procedure-specific Objective Structured Assessment of Technical Skill (OSATS) and time to completion. Participants in the AR group additionally completed the NASA Task Load Index (NASA-TLX) to assess perceived workload associated with AR use.

Results

Thirty-five PGY-1 residents participated (control n = 27, AR n = 8). There was no statistically significant difference between groups in time to completion (control 1.39 ± 0.25 min vs AR 1.35 ± 0.20 min, p = 0.79) or OSATS performance scores (control 0.91 ± 0.06 vs AR 0.86 ± 0.04, p = 0.17). NASA-TLX scores in the AR group demonstrated moderate perceived workload across domains (median composite score 17.5, IQR 13–20).

Conclusion

In this pilot study, AR-enabled remote proctoring for IO access training produced short-term procedural performance comparable to traditional bedside instruction. These findings support the feasibility of AR-based remote teaching in a simulated surgical education setting and justify further study with adequately powered designs.
